Smart Retrofit Fit-Out of Edinburgh Office Building

September 11, 2024

Overview:
This project involved a retrofit fit-out of an existing two-floor office building in Edinburgh. The goal was to integrate new smart systems while ensuring seamless compatibility with existing building systems, such as HVAC and lighting controls.

Solution Overview:
We delivered a comprehensive solution that met all customer requirements, focusing on system design, equipment selection, and integration. The project included the following key components:

  • BMS integration with existing landlord systems.
  • Metering and final circuit monitoring.
  • Lighting control integration.
  • Software development for UUID-embedded QR codes and user interface software.
  • LoRaWAN interface configuration for the sensor network.
  • Deployment of occupancy and wellbeing sensors.
  • Standardizing data using BDNS for MQTT Broker delivery.
  • Full system engineering and configuration.

System Integration:
As the Master Systems Integrator (MSI), we designed and commissioned a Tridium Niagara-based system to unify data from building systems and sensor networks. This data was pushed to an MQTT Broker for the building insights platform to use.

Lighting Controls:
The existing Eaton Cooper lighting system was retained for open-plan office areas, while new DALI lighting was installed in reception, meeting spaces, and demonstration areas. A programmable touchscreen controller integrated with the Tridium platform was provided to manage lighting and offer insights into usage.

HVAC Controls:
The building’s central Trend BMS system and Daikin VRF system for local comfort cooling were integrated using a JACE running the Tyrrell Products Trend Driver. The Daikin system was connected via BACnet, with separate networks for the landlord’s BMS and the client’s IT system.

Sensor Network:
A combination of IP-based people counting and wellbeing sensors, alongside LoRaWAN sensors, were deployed to monitor occupancy, temperature, humidity, and CO2 levels. The data was transmitted via MQTT to the Niagara platform for formatting and onward delivery to the insights platform.

Metering Data:
Sub-metering data from existing Modbus electricity meters was integrated with Tyrrell Final Circuit Monitoring boards, providing detailed consumption data. Water metering was also included for the two floors.

Data Processing:
All data was sent to the building insights platform via MQTT. The UDMI Service Driver in the Niagara platform ensured the data was formatted using BDNS and BrickSchema, making it easily processed by the Smart Building Platform.

Conclusion:
This retrofit project successfully integrated advanced smart systems with existing infrastructure, delivering enhanced control, data insights, and efficiency for the building’s operations.
